Prior to 4.4.3, missing access-control checks on `PUT/DELETE /action/{id}` allow an authenticated user to modify or delete actions on any Layout. Exploitation requires the privilege to allow edits, including deletion, to all created Layouts, which is granted to non-administrators as standard. This issue concerns `Layout actions` rather than the separately reported DataSet export vulnerability. This issue is fixed in version 4.4.3.","categories":["Unclassified"],"product":"xibo-cms","vendor":"xibosignage","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-52729","source_modified_at":"2026-10-28T13:23:13.291Z","fetched_at":"2026-10-28T15:55:58.673066Z","product":"xibo-cms","vendor":"xibosignage","versions":[{"version":"< 4.4.3","status":"affected"}],"defaultStatus":null}],"fixed_versions":[],"cvss":7.1,"severity":"High","kev":{"listed":false},"epss":{"probability":null,"percentile":null,"score_date":null},"published_at":"2026-10-28T13:23:13.291Z","modified_at":"2026-10-28T13:23:13.291Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-52729","fetched_at":"2026-10-28T15:55:58.673066Z","source_modified_at":"2026-10-28T13:23:13.291Z"}],"sources":["CVE List"],"references":[{"source":"CVE List","url":"https://github.com/xibosignage/xibo-cms/security/advisories/GHSA-7j3h-48f7-w4fr","tags":["x_refsource_CONFIRM"]},{"source":"CVE List","url":"https://github.com/xibosignage/xibo-cms/pull/3492","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/xibosignage/xibo-cms/commit/96d7b458781b8cd10e64788565fbdeffd15f08cf","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/xibosignage/xibo-cms/commit/efd13abf868e2386f40929ed6e4f36fead310f20","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/xibosignage/xibo-cms/releases/tag/4.4.3","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/xibosignage/xibo-cms/releases/tag/4.5.0-beta","tags":["x_refsource_MISC"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-28T13:23:13.291Z","content_hash":"53d3aca1fd1991cf09260b5f67fc9af0683fd80df7c55835c3622db144fe8120"}}
